|Subsequent Events [Abstract]|
In July 2019, we issued and sold 6,871,727 shares of common stock at an offering price of $15.28 per share and pre-funded warrants to purchase 2,945,026 shares of common stock at a public offering price of $15.2799 per warrant in an underwritten public offering pursuant to a shelf registration statement on Form S-3. We have granted the underwriters an option to purchase up to 1,472,512 additional shares of our common stock at an offering price of $15.28, less underwriting discounts and commissions. This option has not been exercised by the underwriters and expires 30 days from July 18, 2019. Each pre-funded warrant entitles the holder to purchase one share of common stock at an exercise price of $0.0001 per share and expires in seven years from the date of issuance. The gross proceeds from this public offering were $150.0 million, resulting in aggregate net proceeds of approximately $140.6 million, after deducting underwriting discounts and commissions and estimated offering expenses payable by us.
